MIW1500-Series power modules are low-profile

dc-dc converters that operate over input voltage ranges of

4.5-9VDC, 9-18VDC, 18-36VDC and provide precisely regulated

output voltages of 5V, 12V, {12V and {15V.

for data communication equipments, mobile battery driven

equipments, distributed power systems, telecommunication

equipments, mixed analog/digital subsystems, process/machine

control equipments, computer peripheral systems and industrial

robot systems.

The modules have a maximum power rating of 3W and a typical

full-load efficiency of 82%, continuous short circuit, 60mA output

ripple, built-in filtering for both input and output minimizes the need

for external filtering.

Test Configurations

Input Reflected-Ripple Current Test Setup

Input reflected-ripple current is measured with a inductor

Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 KHz) to
simulate source impedance.

Capacitor Cin, offsets possible battery impedance.
Current ripple is measured at the input terminals of the

module, measurement bandwidth is 0-500 KHz.

Peak-to-Peak Output Noise Measurement Test

Use a Cout 0.47uF ceramic capacitor.
Scope measurement should be made by using a BNC

socket, measurement bandwidth is 0-20 MHz. Position the
load between 50 mm and 75 mm from the DC/DC Converter.

Design & Feature Considerations

Maximum Capacitive Load

The MIW1500 series has limitation of maximum

connected capacitance at the output.

The power module may be operated in current limiting

mode during start-up, affecting the ramp-up and the startup
time.

For optimum performance we recommend 220uF

maximum capacitive load

for dual outputs and 470uF

capacitive load

for single outputs.

The maximum capacitance can be found in the data.

Overcurrent Protection

To provide protection in a fault (output overload)

condition, the unit is equipped with internal current limiting
circuitry and can endure current limiting for an unlimited
duration. At the point of current-limit inception, the unit shifts
from voltage control to current control. The unit operates
normally once the output current is brought back into its
specified range.

Input Source Impedance

The power module should be connected to a low

ac-impedance input source. Highly inductive source
impedances can affect the stability of the power module.

In applications where power is supplied over long lines

and output loading is high, it may be necessary to use a
capacitor at the input to ensure startup.

Capacitor mounted close to the power module helps

ensure stability of the unit, it is recommended to use a good
quality low Equivalent Series Resistance (ESR < 1.0[ at 100
KHz) capacitor of a 8.2uF for the 5V input devices, a 3.3uF for
the 12V input devices and a 1.5uF for the 24V devices.

Output Ripple Reduction

A good quality low ESR capacitor placed as close as

practicable across the load will give the best ripple and
noise performance.

To reduce output ripple, it is recommended to use 3.3uF

capacitors at the output.
